中型货车板簧悬架设计(选题审批表,任务书,开题报告,中期检查表,毕业论文10000字,cad图纸8张合一)
摘  要:悬架是保证车轮或车桥与汽车承载系统之间具有弹性联系并能传递载荷、缓和冲击、衰减振动以及调节汽车行驶中的车身位置等有关装置的总称。悬架最主要的功能是传递作用在车轮和车架之间的一切力和力矩，并缓和汽车行驶过不平路面时所产生的冲击，衰减由此引起的承载系统的振动，以保证汽车行驶的平顺性。本文讨论了汽车悬架的发展现状，对悬架的结构形式进行简单介绍，对影响悬架运动的各种因素进行分析，主要对中型货车板簧悬架的主要参数进行设计计算，包括中型货车前桥钢板弹簧、后桥复合式钢板弹簧、汽车减振器参数的选择计算和横向稳定杆的设计计算。为进一步设计板簧悬架提供了较有价值的资料。

Abstract：Suspension involves some related components, which exist to guarantee elastic contact between wheels or axle and the carrying system. It also has a great contribution in transferring the load, cushioning the impact, attenuating vibration, and regulating the position of the body of the running car. Apart from the transformation of force and moment between wheels and frame, it helps cushion the impact when uneven road surface is encountered, undermine the following vibration of carrying system, as a result, provide a great possibility of smoothly running. This paper discusses the current development of vehicle suspension, gives a brief introduction of the structural form of suspension, analyze factors which have influence on suspension movement. The major part of this paper are calculation and design of leaf spring on front axle of medium truck, combined leaf spring on rear axle, stabilizer bar, as well as choosing the parameters of shock absorber. All of these are preconditions to further design of suspension with leaf spring. [资料来源：www.THINK58.com]
